摘要：This paper refutes the received opinion that the Slavic collective suffix -ьje should be derived from a putative PIE suffix *-iyo-. It is argued that the suffix -ьje is a regular development of the PIE collective formant *-ey- / -i-, discovered by N. Oettinger (1995, 1999). Besides Greek and Hittite, this suffix was preserved in Slavic in its original function; moreover, Proto-Slavic appears to be the only Indo-European language where the suffix remained at least partially productive.
